From rom http://www.powerpostgresql.com/PerfList/
"even in a two-disk server, you can put the transaction log onto the
operating system disk and reap some benefits."
Context: I have a two disk server that is about to become dedicated to
postgresql (it's a sun v40z running gentoo linux).
What's "theoretically better"?
1) OS and pg_xlog on one disk, rest of postgresql on the other? (if I
understand the above correctly)
2) Everything striped Raid 0?
3) <some answer from someone smarter than me>
TIA,
